2006-08-24 12:41:30 PDT -- An Indiana drifter should be executed for brutally raping, sodomizing and killing an Antioch mother of three who had been enjoying her daily walk on a popular Concord trail, a jury decided today.

"We're happy with the outcome," Aiello-Loreck's son, Eric Lyon, 25, told The Chronicle. "It's what we wanted. He deserved to die for what he did to my mom."

Asked if he wanted to say anything to Frazier, Lyon said, "From me? No, I have nothing to say to that guy."

In June, the eight-woman, four-man jury convicted Frazier of first-degree murder, rape and sodomy for killing Aiello-Loreck on May 13, 2003, by dragging her into vegetation and bashing her head at least 10 times with a metal bar. Authorities linked Frazier to the slaying after tests matched DNA from cigarette butts at the scene and the metal bar to the semen recovered from the victim's body.

Several jurors said the DNA evidence left them no choice but to return with a death-penalty verdict.

"We felt the circumstances of the crime far outweighed the mitigating circumstances," jury forewoman Heather Burrows, 40, of San Ramon said. "The brutality of it, we felt, was premeditated. We hope we've spoken for Kathy."

Juror Rick Feliciano, 33, of Rodeo agreed, saying, "We left no stone unturned. There was no reason to give him life in prison."

Juror Maria Duran, 23, of Brentwood said, "Hopefully there can be some closure for the family and she rests in peace."

Cope said Aiello-Loreck was attacked so savagely that her blood turned the dirt off the trail into mud in a daylight assault that would be "rated 'R' for violence and cruelty."

Of the jurors, the prosecutor said, "They gave him more than he gave Kathy. They gave him justice."

Cope said jurors viewed a tape of a police interview of the killer, whom he described as "the worst of the worst."

"When you look at Mr. Frazier speak, it's very clear -- yeah, he's got some issues upstairs, but he knew what he was doing and what he did," he said.

But Downing said her client was sexually, physically and emotionally abused during his childhood and had sniffed gasoline, abused alcohol and used crack cocaine.

Frazier, who was born to teenage parents, suffered from bipolar disorder, attention-deficit disorder and organic brain dysfunction, Downing said.

"Robert Frazier was very ill mentally," she said. "This was not a long, planned-out, premeditated crime. This was an emotional outburst. He lost control."

Downing said she believed Frazier should have been spared the death penalty.

"The truth of the matter is, there's good in him," she said.

Minney is scheduled to formally sentence Frazier on Oct. 27. When the judge asked Frazier if he was waiving his right to be sentenced in 20 days, he replied, "Sure, whatever."
